Automate GitHub like a pro: Build your own bot with TypeScript and Serverless

Question

Maintaining a repo is more than just writing code.
You label issues, respond to PRs… and somehow keep track of all the // TODO comments scattered across the codebase.

I got tired of juggling all this manually. So I built a bot.

Meet AutoMaintainer-bot

It’s a lightweight GitHub App built with Probot and deployed serverlessly on GCF. Here's what it does:

• ️ Automatically labels issues based on their content
• Welcomes new contributors when they open their first issue
• Scans code for // TODO: and creates issues for them
• Runs entirely serverless — zero infrastructure needed

And yes, it works across multiple repositories.

️ Tech stack

• TypeScript for clean, typed logic
• Probot to handle GitHub events with ease
• Google Cloud run function for instant serverless deployment
• GitHub App with custom permissions
• Optional: YAML config to tweak behavior per repo

Why this matters

• Automating boring tasks = more time to build
• Improves contributor experience
• Encourages TODO discipline
• Serverless = no ops burden
